COMBINED MUFFLER AND STOVE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed December 11, 1905. Serial No. 291,219.

To all whom it may concern:

Be it known that I, WALTER C. S'IRANG, a citizen of the United States,and a resident of Yonkers, in the county of W estchester and State ofNew York, United States of America, have invented certain new and usefulImprovements in a Combined Muffler and Stove, of which the following isa specification.

My invention relates to a combined muffler and stove and its object isto make use of the exhaust gases of an engine.

I will describe my invention in the following specification and pointout the novel features thereof in claims.

Referring to the drawing, Figure 1 is a sectional side elevation of asimple form of my invention. Fig. 2 1s a plan view of the deviceillustrated in Fig. 1. with the cover removed. Fig. 3 is a sectionalside elevation of a modified form of my invention, and Fig. 4 is a planView of the parts shown in Fig. 3 with the cover removed. Fig. 5 is asectional elevation of a boat showing diagrammatically an engine and myinvention combined therewith.

Like characters of reference designate corresponding parts in all of thefigures.

l0 designates an engine. This may be of any desired type which hasexhaust gases passing from it while it is running, such as a steam orinternal combustion engine. 11 designates the exhaust pipe leading fromthe engine.

20 designates my improved muffler which is connected in the exhaust pipe11 in a well known manner.

I will now describe the form of luulllcr which is illustrated inFigs. 1. and 2. In this case the muffler is provided with an internalchamber 21, having a tortuous passage for the gases. Projecting ribssuch as 22, 23 and 24 may be placed within this chamber for the purposeof forming such tortuous passages. The form of this exhaust chamber andthe passages for the gases, however, is an unimportant part of myinvention and they may be made of any desired design or according to anydesired method, many of which are well known in the art. The top 25 ofthe muffler, however, is made with a flat surface, in this case circularin form, with a depression 26 around its outer rim. A cover 30 may beprovided and arranged to fit closely around this rim 26, and the covermay be further provided, if desired, with a lifting handle 31. It ispreferable to make this handle of material which is a non-conductor ofheat. It is desirable to have the form of the muffler and its internalchamber 21 so designed as to cause the surface 25 to radiate the heatfrom the gases readily. To accomplish this purpose I arranged thepassages for the gases so that the hot gases will be blown directlyagainst the inside of the portion of the muffler of which the surface 25forms the outside.

In the form of muffler shown in Figs. 3 and 4 the internal chamber 21for the exhaust gases may be made, as before described, in any desiredform or according to any desired method. In this case the fiat surface25 is provided as before described, but a pertion 27 of the mufileritself is carried up around and above this flat surface 25. This portionmay be made hollow and this hollow portion 28 may be a part of theinternal chamber 21. I sometimes arrange the inside of the portion 27with projecting ribs 29, which, if desired, may also be made hollow asshown at 29 and the hollow portion of these ribs may communicate withthe chamber 28. The cover 30 may be arranged to fit around a rim 26which is provided on the top of the portion 27, and this cover may beprovided with a handle 31 as before. I sometimes also add a hinged door32 in the side of cover 30 and this d0or, if desired, may be providedwith a latch or lock 33. 27 designates a grating which may be placed onthe top of the portion 27 if desired.

It is a well known fact that mufilers, through which the exhaust gasesfrom engines pass, become heated sometimes to a high degree by theexhaust gases. This is especially true of internal combustion enginessuch as gas or gasolene engines.

The devices above mentioned are provided for thepurpose of reducing thenoise caused by the operation of such engines and the heat produced inthe mufllers is entirely wasted. lion to provide means for reducing thenoise of such engines in many of the ways well known in the art and toconstruct such a device in such a form that the heat which is producedin them may be used for heating or cooking purposes. The flat portions25 and 25 i on the top of my inrproved muffler and stove are suitablefor holding dishes or articles to be cooked, ant when the covers 30 or30 are provided, the heat above the surfaces 25 or 25 will be radiatedthereby and the cooking effect of this arrangement increased.

In the form of my invention which is illustrated in Figs. 3 and 4 thesolid ribs 29 or hollow ribs 29 serve to increase the efficiency of thisarrangement as they radiate the heat into the portion of this deviceimmediat ely above the flat surface 25 In this arrangement it is alsopossible to cook a number of articles at once as suflicient heat isgenerated from an ordinary engine to heat a large surface. The grating2T makes it possible to utilize more of the available space, and thedoor 32 in the cover 30 provides a convenient means of access to theportion of this device above the grating 27.

This invention may be used,. as stated before, in conjunction with steamengines. It is particularly adaptable, however, for use in conjunctionwith internal combustion engines such as are in common use on boats andautomobiles. Its use is particularly advantageous when installed on aboat which is used for cruising, or on one where cooking is often done.

It is the purpose of this inven-' What I claim is,

1. A devicc for mullliur; the exhaust gases from an in ternal combustionengine, said device being constructed to form a chamber having tortuouspassages for said gases, :1 [lat radiating surface, a cover for saidradiating surface, and a door in said cover.

2. A device for mullling the exhaust gases from an internal combustionengine, said device comprising \valls arranged to form a chamber forsaid exhaust gases. one of said \valls-formim, a flat radiating surfaceabove said chamber, and other walls forming radiating surfaces above andsurrounding said flat surface.

3. A device for muliling the exhaust gases from an internal combustionengine. said device comprising walls arranged to form a flat.lddllll'lllg surface, and other radiating surfaces above and surroundingsaid fiat surface, the walls being; constructed to form a chamber forthe exhaust gases within all of said radiating surfaces,

4. A device for muilliu the exhaust gases from an internal combustionengine, said device comprising a Hat \vall forming a radiating surface,hollow portions formim, radiating surfaces above and surrounding saidflat surface. said hollmv portions being provided with hollow inwardlyprojecting ribs. the device being constructed to form a chamber for theexhaust gases within all of said radiating, surfaces.

A device for mullliue the cxha gases from an internal combustion engine,S'liil device comprisiug a flat wall forming a radiating, surface,hollow portions tormin riuliating, surfaces above and surrounding saidflat surface. said hollow portions provided with inwardly projectine;ribs, the device being, constructed to form a chamber for the exhaustgases Within all of said radiating surfaces, a grating above theradiating surfaces, and a removable cover for the radiating surfaceabove the grating.

(i. A device for mulliing the exhaust gases from an in ternal combustionengine, Said device comprising a flat \vall forming a radiating surface.hollow portions forming other radiating surfaces above and surroundingthe llat surface, said hollow portions provided with hollow inwardlyprojecting ribs, the device being constructed to form a chamber for theexhaust gases within all of said radiating surfaces and ribs. a gratingabove the radiating surfaces, and a removable cover for the radiatingsurface above the grating and a door in the cover.

7. A device for mufiling; the exhaust gases from an internal combustionengine, said device being construcled or walls arranged to form achamber, with ribs altcrnatcLv projecting from opposite sides of theinner surfaces ol" said walls to form tortuous passa les for the gases,and a llat wall forming a radiating surface above a portion of saidchamber and surrounded by other portions oi the chamber walls.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing \vil'ncsscs. WALTER C, S'LHANG.
